Smoke and heat exhaust ventilator

ABSTRACT

The present invention provides a smoke and heat exhaust ventilator, which includes a pedestal, a diversion cover and a horizontal fan blade. The pedestal is provided with an assembly portion and external surface with an air vent. The diversion cover is assembled onto the external surface of the pedestal being hollow and being provided with an accommodating space, the inner end of which is connected to the air vent. The diversion cover is also provided with a lateral air inlet/outlet connected to the accommodating space. The horizontal fan blade is mounted into the accommodating space and comprised of a rotating shaft and a few blades. The external side of the horizontal fan blade aligns with the lateral air inlet/outlet of the diversion cover, whilst the inner end of horizontal fan blade aligns with the air vent of the pedestal.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a smoke and heat exhaustventilator, and more particularly to an innovative ventilator with apedestal, a diversion cover and a horizontal fan blade.

2. Description of Related Art Including Information Disclosed Under 37CFR 1.97 and 37 CFR 1.98

To ensure smooth air ventilation in a stuffy indoor environment, theroofing structure is often provided with a conventional ventilator 10 asshown in FIG. 1, where some blades are arranged at intervals around thisspherical body to form circular air vents 11. When circular air vents 11are rotated directionally, external air could be guided for ventilationand heat exhaust; however, the following shortcomings are observedduring actual applications:

1. A bigger space shall be required since the conventional ventilator 10has a spherical shape along with its base at higher location. Thus, apoorer aesthetic effect will be caused when it is mounted externallyonto the roof.

2. The wind resistance coefficient is relatively increased due to thehuge spherical shape of conventional ventilator 10, this makes itvulnerable to wind interference, e.g. wind gusts, typhoons. Meanwhilenumerous unwanted materials (e.g. newspaper, plastic bags, fireworks andkites) are possibly jammed at the circular air vent 11, leading to apoorer ventilation effect.

3. As the circular air vent 11 is composed of circular blades, rainwatermay leak through the vent, bringing about indoor water accumulation.

Thus, to overcome the aforementioned problems of the prior art, it wouldbe an advancement in the art to provide an improved structure that cansignificantly improve efficacy.

Therefore, the inventor has provided the present invention ofpracticability after deliberate design and evaluation based on years ofexperience in the production, development and design of relatedproducts.

BRIEF SUMMARY OF THE INVENTION

The flat structure of the smoke and heat exhaust ventilator of thepresent invention dramatically reduces the height and space of the smokeand heat exhaust ventilator A, thus cutting down the wind resistance fora lower probability of damage to the smoke and heat exhaust ventilatorA.

The aesthetic property of the smoke and heat exhaust ventilator of thepresent invention is an improvement due to smaller height and spaceafter assembly onto the roof.

The lateral air inlet/outlet blocks water infiltration and preventsleakage.

The curved baffle plate is arranged within the lateral air inlet/outletof the diversion cover so that a water-retaining effect is enhanced.

A solar panel 50 is mounted onto the pedestal 20 and diversion cover 30.The smoke and heat exhaust ventilator A can absorb solar energy forenvironmental-friendly power generation.

Although the invention has been explained in relation to its preferredembodiment, it is to be understood that many other possiblemodifications and variations can be made without departing from thespirit and scope of the invention as hereinafter claimed.

DETAILED DESCRIPTION OF THE INVENTION

The features and the advantages of the present invention will be morereadily understood upon a thoughtful deliberation of the followingdetailed description of a preferred embodiment of the present inventionwith reference to the accompanying drawings.

FIGS. 2-3 depict preferred embodiments of the smoke and heat exhaustventilator of the present invention. These embodiments are provided onlyfor explanatory purposes with respect to the patent claims.

The smoke and heat exhaust ventilator A comprises a pedestal 20,defining an assembly portion 21 and an external surface 22. An air vent23 is reserved at a preset location of the external surface 22.

A diversion cover 30 is assembled onto the external surface 22 of thepedestal 20. The hollow diversion cover 30 forms an accommodating space31 with an inner end. The inner end is connected to air vent 23 of thepedestal 20. The diversion cover 30 is provided with a lateral airinlet/outlet 32 connected to the accommodating space 31.

A horizontal fan blade 40 is mounted into the accommodating space 31 ofthe diversion cover 30. The horizontal fan blade 40 comprises a rotatingshaft 41 and a few blades 42 radially arranged onto the rotating shaft41. The blades of the preferred embodiment are arranged radially throughthe rotating shaft 41. The external side of the horizontal fan blade 40aligns with the lateral air inlet/outlet 32 of the diversion cover 30,while the inner end of horizontal fan blade 40 aligns with the air vent23 of the pedestal 20.

The pedestal 20 is a plate, and an oblique surface 24 is formed inperipheral.

A curved baffle plate 33 is placed within lateral air inlet/outlet 32 ofthe diversion cover 30 with a predefined depth. The curved baffle plate33 is formed when the external surface 22 of the pedestal 20 protrudesuntil the external surface 22 exceeds the center of rotating shaft 41 ofthe horizontal fan blade 40.

The diversion cover 30 is provided with an oblique flange 34 opposite tothe lateral air inlet/outlet 32, thereby serving the purpose of guidingair flow.

Based on above-specified structures, the present invention is operatedas follows:

Referring to FIG. 3, external wind could be guided from lateral airinlet/outlet 32 into the inner space via horizontal fan blade 40.Conversely, indoor air could be guided outside of the lateral airinlet/outlet 32 via the horizontal fan blade 40.

The assembly of the present invention is illustrated below:

Referring to FIG. 4, the smoke and heat exhaust ventilator A isassembled onto the surface 60 of the roof for ventilation and heatexhaust.

Referring to FIG. 5, the smoke and heat exhaust ventilator A can also beassembled onto the ridge 61 of the roof for ventilation and heatexhaust.

Referring to FIG. 6, the smoke and heat exhaust ventilator A can also beassembled between the edge 62 of eave and the wall 63 for ventilationand heat exhaust.

Referring to FIG. 7, the smoke and heat exhaust ventilator A can also beassembled onto a preset location of the vertical wall 64 of thebuilding.

Referring to FIG. 8, a solar panel 50 is mounted onto the pedestal 20and diversion cover 30, so that solar energy can be absorbed forauxiliary power generation.
